From Carew and Mylroie, 1995a. 3 INTRODUCTION The purpose of this field guide is to introduce the participant to the geology and geomorphology of the Bahamas (Fig.1) as seen on San Salvador Island (Fig. 2), by visiting various localities exposed primarily along the perimeter of the island. The stratigraphy used in this guide (Fig. 3 and Table I) is that of Carew and Mylroie (1995a; 1997). This stratigraphic sequence comprises depositional units that were deposited as a result of sea level changes during the Quaternary. A general geologic map of San Salvador Island is shown in Figure 4.
